Asked what the central limit theorem says, a student replies, As you take larger and larger samples from a population, the histo

gram of the sample values looks more and more Normal.
Is the student right?

A. No. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means.
B. Yes. This is exactly what the theorem says

Answer:

A. No, the student is not right. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means.

Step-by-step explanation:

No, the student is not right. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means. The central limit theorem says that if we take a large sample (i.e., a sample of size n > 30) of any distribution with finite mean \mu and standard deviation \sigma, then, the sample average is approximately normally distributed  with mean \mu and variance \sigma^2/n.

One factor of the polynomial 3x3 + 20x2 - 21x + 88 is (x + 8). what is the other factor of the polynomial? (note: use long divis
Snezhnost [94]

The other factor of the polynomial is a. 3x2-4x+11

Given polynomial is 3x3 + 20x2 - 21x + 88 and the factor is (x+8)

We need to find another factor using long division method

So,

We will divide the polynomial by the factor to find the another factor

Therefore,

\sqrt[x+8]{3x^3+20x^2-21x+88}

Now calculating

First multiplying 3x^2 with (x+8) so , 3x^2 will be in the quotient

We get 3x^3+24x^2

simplifying the calculation for 3x^3+20x^2 and 3x^3+24x^2

We get the remainder is -4x^2-21x+88

Second we will multiply -4x with (x+8) Where -4x will be in the quotient

We get -4x^2-32x and then we will simplify the equation

We get 11x +88 as a remainder

The quotient we get is 3x^2-4x

Third we will multiply +11 with (x+8) Where +11 will be in the quotient

we get 11x+88

Simplifying the equation we get the remainder 0

So the quotient we get is  (3x2 - 4x+11)

Hence the another factor of the polynomial is  (3x2 - 4x+11)
